Why Sinai Construction Engineering Hillside Repair?

Sinai Construction Engineering will do whatever work is necessary to ensure that your hillside foundation will not collapse or crumble under the weight of your house or building, that your home or building will not slide off its foundation, and that your foundation will not slide off the slope or the side of the hill.

Our field operators are current with and trained to use state-of-the-art equipment and the most efficient excavating and grading techniques. We also offer specific, specialized services that are often required in hillside foundation work such as excavation, foundation trenching, backfilling, and compaction.

We are qualified and certified to perform deep foundation work, whether hand dug, drilled or driven. As foundation specialists, we work closely with soils and geotechnical engineers and are always attentive to soils conditions.

Los Angeles Hillside Foundation Repair Typical Components

Caissons or Piles

A pile is used to carry or transfer the load of a structure to the bedrock below the ground surface. Whenever possible, drilling is accomplished by using heavy machinery with an auger attachment. Sometimes, however, specific site conditions dictate that the shafts be hand-dug.

For a typical caisson, a round hole is dug or bored into the bedrock. A steel cage of reinforcing bars is then constructed and placed into the hole. Then – following inspections by the soil engineer, the structural engineer and the building inspector – concrete is poured into the caisson around the steel reinforcing cage.

Grade Beams

A grade beam is a continuous reinforced concrete beam that distributes the load to bearing points (such as pile caps or caissons) or transfers the load to the ground. When used as continuous interior floor supports, grade beams provide strong support with respect to seismic movement.

"Sinai Construction has literally saved our home and the homes of our two neighbors from sliding off a steep cliff. After interviewing 3 other companies we chose Sinai due to their extensive experience and reputation. The work involved an extremely complicated caisson work that went as deep as 70 feet. Our structural engineer who is a UCLA professor was very complimentary upon the completion of work as to the abilities of Sinai's crew to deliver this complicated work on time and budget and without any corrections needed from him."
